3. Gait recording detailed description

3.1

The PhysiGait Lab is delivered with 2 rubber clips as default accessory. Elastic foot straps

can be bought from the web-shop (shop.gaitup.com) if needed, for example to measure

barefoot gait.

To insert the Physilog®5 into the rubber clip, slide the sensor into the clip on one side then

carefully pull the rubber of the opposite side to cover the edge of the Physilog®. The USB

entry of the Physilog® should be oriented in front of the clip opening, so that the sensor can

be charged without removing the clip.

For gait measurement the sensor can be fixed in any orientation on the foot, either in the

shoelaces or on the outer side of the shoe (on the inner side there is a risk of disturbing the

gait). The computed gait parameters will not be influenced by the sensor position. Fix the

sensor such that it doesn't move with respect to the foot / shoe.

3.2

To start the sensor, push the main button for about 3 seconds. The LED becomes green

and stops again, at this moment you can release the button. It doesn't matter which

Physilog® you turn on first.

For firmware version 1.0.4, the "master" sensor will start to blink green immediately, the

slave sensor shows a continuous green light until it has obtained the synchronisation signal

which starts its recording ("Initializing" in the illustration above).

For later firmware versions (v1.1.0 upwards, released June 2017), both sensors start to

blink from the start, when they are synchronized the blinking is simultaneous. To better see

if they are synchronized it is recommended to start the sensors with a short lag between the

starts.

In all cases wait until the two sensors blink green simultaneously before starting the

movement. The best practice is to start the sensors when they are already attached to the

foot. Otherwise turn them on just before fixing on the subject and ask the subject to stand

still for 5 seconds with the Physilog
